Abstract
We first find the combinatorial degree of any map f:V→F, where F is a finite field and V
is a finite-dimensional
vector space over F. We then simplify and generalize a certain
construction, due to Chein and Goodaire, that was used in
characterizing code loops as finite Moufang loops that possess at
most two squares. The construction yields binary codes of high
divisibility level with prescribed Hamming weights of
intersections of codewords.
